Without grain, elevators aren't necessary

To restate the obvious, the bread-basket of the world needs storage facilities that can be used as a transfer point from farm to the rest of the world, including stops at flour mills, processing plants, etc. But without the grain to harvest, it all becomes redundant. Anyway, I thought a photo of a typical wheat field in Saskatchewan (taken late August 2006) would help to set the scene, so to speak.
